Species composition, similarity and diversity in three successional stages of a seasonally dry tropical forest

TL;DR: The floristic composition, species diversity, similarity and richness among three stages of forest regeneration, and the influence of past land use and the frequency of anthropogenic disturbances on species composition in a seasonally dry tropical forest in northwestern Costa Rica are described.
Journal ArticleDOI

Continuous wavelet analysis for the detection of green attack damage due to mountain pine beetle infestation

TL;DR: In this paper, the authors used a continuous wavelet transform to detect green attack damage in lodgepole pine needles by means of hyperspectral measurements, particularly via continuous wavelets analysis.
Journal ArticleDOI

Ecological fingerprinting of ecosystem succession: Estimating secondary tropical dry forest structure and diversity using imaging spectroscopy

TL;DR: In this article, the authors evaluated the use of EO-1 Hyperion hyperspectral satellite imagery for mapping structure and floristic diversity in a Neotropical tropical dry forest as a way of assessing a region's ecological fingerprint.
Journal ArticleDOI

Hyperspectral discrimination of tropical dry forest lianas and trees: Comparative data reduction approaches at the leaf and canopy levels

TL;DR: In this paper, a dataset of spectral signatures (leaf level) of tropical dry forest trees and lianas and an airborne hyperspectral image (crown level) are used to test three hypersensorral data reduction techniques (principal component analysis, forward feature selection and wavelet energy feature vectors) along with pattern recognition classifiers to discriminate between the spectral signatures of liansas and trees.
